5 Claims.

The present invention relates to a temperature regulating valve and has for its prime 'object to provide means whereby hot and cold water may be mixed so that water of the desired temperature may be readily maintained when being used for various purposes where a constant temperature is desired.

Another very important object of the invention resides in the provision of a temperature regulating valve of this nature which is easy to adjust depending upon the temperature desired.

A still further very important object of the in- Vention resides in the provision of a temperature regulating valve of this nature which is comparatively simple in its construction, compact and convenient in its arrangement of parts, not likely to easily become out of order, thoroughly eflicient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention consists in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a longitudinal sectional view taken substantially on the line |-l of Figure 2.

Figure 2 is a similar section taken at right angles to that shown in Figure l substantially on the line 22 of Figure 1,

Figure 3 is a detail transverse section taken substantially on the line 3-3 of Figure 2,

Figure 4 is a perspective view of the heat responsive element or thermostat,

Figure 5 is a plan view of another embodiment of the invention,

Figure 6 is a sectional view taken substantially on the line 6-6 of Figure 7,

Figure 7 is a sectional view taken substantially on the line 7-1 of Figure 6,

Figure 8 is a detail section taken substantially on the line 8-8 of Figure 6.

Referring to the drawings in detail and first particularly to the embodiment of the invention shown in Figures 1 to 4 inclusive, it will be seen that I have provided a circular mixing chamber 5 from which radiates .outwardly an extension 6 terminating in the internally threaded outlet opening '4. A removable cap 8 is provided for the mixing chamber 5 being held in place by suitable means such as screws 9. A headed pin Ill is threadedly engaged in the center of the chamher and has rockable thereon a Y-shaped gate Y. 7

thereof which is disposed in the slot l6.

This gate Y comprises a pair of diverging wings H-il merging with stem l2. The wings H are provided with openings 14 through which the water may fiow. A pair of openings l5--l5 are provided in the wall of the chamber in spaced relation to each other and adjacent to each other and opposed to the extension 6 and are adapted to be partially closed by the ends of the wings It, said ends being slightly more spaced apart and slightly broader than the opening IS. The stem- I2 is rockable intermediate its ends on the pin H). A slot it extends inwardly from the extremity of the stem. Numeral ll denotes an elongated bi-metal heat responsive element or thermostat with a the pin IE on the extremity The other end of this element I! is fixed in the outer portion of the extension 6 as indicated at I9. A screw 20 is threaded through one side of the extension 6 and has a swivel engagement 2i with an intermediate portion of the element l'l so that this element may be adjusted.

As the hot and cold waters flow through the openings I5 into the chamber they will be mixed and contacted with the element ll causing the same to bend'and rock the gate Y so as to adjust the wings ll thereof with respect to the openings i5 so that the proper temperature of the mixture may be had which is flowing through the outlet l".

Now referring to the other embodiment of the invention disclosed in Figure 5 it will be seen that numeral 5 denotes the mixing chamber, numerals l5, I5 the hot and cold inlet openings, numeral '8' the outlet opening directly from the chamber, and the letter Y denotes generally the gate. This gate includes the wings H, H cooperating with the openings l5 similar to the first mentioned embodiment. An opening H3 is provided in the crotch of the gate to permit the passage of water. The stem l2 terminates in a cylindrical casing 30 rockable on a pin ill mounted in a wall of the chamber 5. In this casing 36 there is a spring 32 having one end fixed to the pin and coiled about the pin and the other end fixed in the casing and is tensioned to normally urge the gate Y in a clockwise direction with respect to Figure 6.

Numeral ll" denotes a crescent shaped heat responsive element which in the present instance is hollow and adapted to be filled with compressed air or gas. One end of this crescent shaped element is pivotally' mounted as at 33 in the chamber 5 and curves about the casing and on the other end thereof there is fixed a chain 36 which extends partially about the casing 36 and is anchored thereon as at 38. A

pivot 33 and is threaded through the wall of the chamber .so that the heat responsive element may be adjusted in accordance with the desired temperature of the water.

As the hot and cold water flows into the mixing chamber and contacts with the heat responsive element the same will change its curvature depending upon the temperature of the mixture and will either pull on the chain 34 so as to rock the gate in one direction or slacken the chain so that the spring will rock the gate in-the other direction.- 1

With either of the embodiments a valve or faucet must be used near the outlet for this device only controls the temperature and doesnot stop the vfiow of water completely at any time.

. Use of valves on eachinlet pipe would improve of construction, and in the combination and arrangement of parts-may be resorted to without departing from the spirit or scope of the inventions as hereinafter claimed or sacrificing any of its advantages.

Gates Y and? are spaced from the walls of the respective chambers 5 and 6' by washers 40 and III on the pins II and it which washers bear against the wall of the chamber.
